Product Description:
The Masoneilan pneumatic actuator diaphragms are original equipment manufacturer (OEM) replacement parts specifically designed for the Type 87/88 spring-diaphragm actuators as well as the Camflex eccentric rotary plug valve actuators. These diaphragms act as a vital flexible barrier that transforms air pressure into mechanical thrust. This function is crucial as it directly impacts the actuator’s accuracy in response, the force applied to seating, and its durability over extended periods.
Within this product range, the model 035106040-716-0000 is intended for Camflex and eccentric rotary valve actuators. It is crafted from Nitrile (Buna-N) material reinforced with polyester to offer exceptional resistance to oils and enhanced mechanical strength. Additionally, models 010864-003-779, 010865-003-779, 010866-003-779, and 010867-003-779 are tailored for the 87/88 series actuators, featuring nominal diameters of 300 mm, 370 mm, 475 mm, and 550 mm, respectively. These diaphragms are molded using fiber-reinforced nitrile rubber, ensuring consistent actuation response, superior leak-proof sealing, and robust resistance to corrosion caused by process fluids.
These diaphragms are engineered to support operating pressures up to 150 psi while functioning efficiently across a temperature range spanning from -40°F to 180°F (-40°C to 82°C). This versatility makes them ideal for a wide variety of industrial control valve applications. Moreover, the multi-spring diaphragm actuator design enables field reversibility and dependable performance across services with low to high pressure drops.
Features:
This product serves as an OEM replacement fit, designed specifically as a direct substitute for Masoneilan 87/88 series actuators as well as Camflex and eccentric rotary plug valve actuators. It ensures compatibility and seamless integration without the need for modifications.
Constructed from fiber-reinforced nitrile rubber, the material offers exceptional tensile strength and resistance to oil. Additionally, it maintains dimensional stability even under frequent flexing, making it highly durable in demanding applications.
For the Camflex type, polyester reinforcement is incorporated to enhance both burst strength and fatigue life. This feature is crucial for meeting stringent cycle requirements in various industrial operations.
The actuator utilizes a molded rolling diaphragm design which guarantees low friction during operation, smooth travel along its stroke, and consistent actuation force. This design contributes to reliable and efficient performance.
Equipped with high leak-proof sealing, the product effectively prevents air bypass, ensuring precise pressure-to-thrust conversion and improving overall actuator responsiveness.
With a pressure rating of up to 150 psi, this product is suitable for standard pneumatic actuator supply pressures, making it versatile across different control system configurations.
It operates efficiently within a temperature range from -40°F to 180°F, accommodating a wide spectrum of ambient and process conditions commonly encountered in industrial environments.
The nitrile compound used in its construction offers excellent corrosion resistance against oils, greases, and numerous process fluids typically found in control valve services, thereby extending the actuator’s service life.
Available in multiple diameter options including 300 mm, 370 mm, 475 mm, and 550 mm, it caters to various actuator sizes and thrust requirements, providing flexibility for different applications.
Proven in the field for its reliability, this product is engineered to maintain stable activation responses and significantly enhance the longevity of valve operation.
